Cryptoloop is not the only user of loop transfer interface. Please don't
change that interface as it breaks code outside of mainline kernel.

Cryptoapi interface is quite broken. Your change extends that breakage to
loop transfer interface. Please don't do that.

Linus, please don't apply this patch.
